If massive invisible particles are pair-produced in a three-body decay, then the energy distribution of the other (visible) product is sensitive to the mass of the invisible pair. We use this fact in the contexts of a Higgs boson decaying into (i) a Z-boson and two massive neutrinos of a fourth generation, and (ii) a Z and two lightest supersymmetric particles in the minimal supersymmetric stan...

dear editor:   hehua ye and colleagues reported an interesting and rare case of primary conjunctival rhabdomyosarcoma (rms) successfully treated with surgery and chemotherapy in iranian journal of ophthalmology 201123(4):65-68. there are some considerable comments that i would like to point out.   orbital rms is the most common malignant mesenchymal neoplasm of the childhood and may also rarely...

Torque balancing for diesel engines is important to eliminate generated vibrations and to correct injected quantity disparities between cylinders. The vibration phenomenon is important at low engine speed and at idling. To estimate torque production from each cylinders, the instantaneous engine speed from the crankshaft is used. Currently, an engine speed measurement every 45° crank angle is su...

This study aimed to determine the bacteriological pattern and antimicrobial susceptibility of diabetic foot ulcer (DFU) infections seen in our practice, with a view to suggesting optimal therapy for these patients. Forty-seven persons with DFU were seen. The mean age was 56 years. Of these, 30 (64%) had wound swabs sent for bacteriological assessment and antibiotic sensitivity patterns. There w...

A mechanism is proposed and evaluated for driving rotation in tokamak plasmas by minority ioncyclotron heating, even though this process introduces negligible angular momentum. The mechanism has two elements: First, angular momentum transport is governed by a diffusion equation with a non-slip boundary condition at the sepatratrix. Second, Monte-Carlo calculations show that energized particles ...

The purpose of this paper is to study how the consideration of several criteria, as opposed to a more traditional mono-criterion approach, helps the modelling of imprecision, uncertainty and inaccurate determination (I.U.I.D.) in a decision-aid study. After a brief review of the main sources of inaccurate determination, uncertainty and imprecision that arises in a decision-aid situation, we sho...

2014 The magnetocaloric effect has been used to determine the phase diagram (H, T) of a CuMn spin glass. Our results suggest the presence of two lines : the spin glass-paramagnetic boundary line Hc(T) and a crossover line Hm(T) separating a pure Curie paramagnet from a non-Curie paramagnet. The data obtained for the derivative (~M/~T)H obey a scaling law and give an estimation of the critical e...

This paper will present the first draft of the University of Vienna ePortfolio framework which is closely interlinked with the university-wide eLearning strategy. Conceptually the aim of the framework is to bridge the gap(s) between different ePortfolio conceptualisations, integrate ePortfolio on a curricular level in the context of a university-wide community for knowledge production, and envi...
